Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

DENVER — A small startup claiming breakthroughs in phase-coherent filter modulation will be demonstrating its signal-processing techniques in analog pager bands later this year, as a prelude to ...

Optical vector analysis has emerged as a critical tool for characterising optical devices, enabling simultaneous measurement of amplitude and phase responses over wide bandwidths. This technique is ...

This paper is the study of the QPSK (Quadrature Phase Shift keying) modulation technique using AWGN (Additive White Gaussian Noise) and Multipath Rayleigh fading channel. In QPSK scheme the authors ...

Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich (TUM) claim to have used a new modulation technique to transmit data at 1Tbit/s on an optical fibre network. This was ...

BE has put a name on its new 50 kW AM transmitter, first reported here in July. The company will show its 4MX 50 AM transmitter at the NAB Radio Show. The model name refers to a Fourier Modulation (4M ...

Power-density improvements are an increasingly elusive goal as designers exhaust the easiest or most obvious solutions. One direction that’s now being explored more thoroughly is advanced modulation ...
